Remarks
The HTMLDocument property of the HTMLTaskPane object is one of the properties inherited by the TaskPane object when the type of the task pane is 0, which means that it is the custom task pane.
Using the HTMLDocument method, you can call scripting functions contained in the HTML code of the task pane from the primary scripting file of a form, and you can also directly manipulate the HTML code of the task pane using any of the properties and methods that the HTML document object provides.
Example
In the following example, the HTMLDocument property of the HTMLTaskPane object is used to set a reference to the HTML document object of the custom task pane. Then the code calls the TaskPaneSwitchView custom function that is defined in the HTML code of the custom task pane.
var objHTMLDoc;
objHTMLDoc = XDocument.View.Window.TaskPanes(0).HTMLDocument;
objHTMLDoc.parentWindow.TaskPaneSwitchView();
